It is the object therefore, of our invention In the accompanying drawing, 1 indicates "65 to provide a container from which a desired the body of the container which holds a amount of mustard can be dispensed when supply of mustard. Said container may be required and in which the contents of the made of glass, porcelain, china 'or of any container are kept covered and unaffected by other suitable material which is not affected air or exterior conditions. I by the mustard or such other contents as 70 It is well understood that it is extremely may be placed within it.

ing drawing, in which The upper end of the rod or stem Gtermt nates in a knob 13 adapted to be engaged by the hand of the user for actuating the piston to force mustard out through the outlet opening 3 upon a sausage, sandwich or other article. The stem or rod 6 and consequently its attached piston 1 is normally thrust upward by the impulse of a spring 10 which bears against a stop 9 secured on the rod and which is contained within a casing 11 secured to the underface of the cover 12.

At 8 is shown a disk-shaped plate which. is provided with a central opening 14, through which the rod or stem 6 passes. Said opening 14 in the disk 8' is larger in diameterthan the stem 6 so that the disk is therefore loosely held upon the stem 6 and is free to slide thereon as required. Said disk 8 is prevented. from falling free of the stem 6 by an abutment in the nature of a nut 7 or similar stop.

It will thus be seen that the disk 8 is located between the underface of the piston 4t and the stop 7, the space between these two elements being suiiicient to allow the'disk considerable movement so that when said disk is in the position shown in Figure 1 and is away from the underface of the piston 4, mustard can freely move through the perforations in the piston and pass down in the chamber 2 towards its outletopening 3. Said outlet opening 3 is preferably provided in a thickened end part of the chamber 2 so that said opening 3 is of considerable depth and the mustard must be forced through it with, some pressure and thus greater quantities of mustard will not be removed from the container than are required for application to an article of food. The depth of the outlet opening 3 thus provided, aids considerably in the pumping action of the device in feeding mustard below the piston with subsequent ejection thereby.

From the foregoing, the operation of our improved device will be readily understood. Assuming that the device is, filled, or partly filled with mustard. Under the impulse of the spring 10', the stem 6 is moved upwardly and its attached piston 4 is consequently moved upward in the chamber. When this occurs, mustard is forced through the open ings 5 in the piston 4 and the same oozes downward past the edge of the disk 8 and into the lower part of the chamber 2. The outlet opening 3 is so minute and its depth is so great that the mustard, which flows extremely sluggishly, will not drip out and consequently, no closure means for the opening 3 is required.

To eject mustard from the container out of the opening 3, the knob 13 on the end of the stem 6 is simply pressed downward and the mustard in the lower end of the compartment 2, and which was subsequently fed thereto by the upward movement of the piston as shown in Figure 1, is forced through the opening 3 as shown in Figure 4.

It will be seen that the pressure of the mustard in the lower part ofthe chamber 2, which mustard is indicated at 15, against the underface of the disk 8, causes said disk to be moved upwardly against the underside of the piston f to cover the openings 5 therein. Thus, when the piston a is moved toward the outlet opening 3, the same is completely closed and acts effectively as a plunger against the mustard 15', to force the same through the opening 3 iii small quantities as are required for application to a sausage, sandwich or the like.

It will be seen also that the piston in moving either-to or from the outlet opening 3 tends to force mustard towards said; open-. ing through the said piston as it moves away from the opening,- feeding mustard below it and into the chamber 2 and as it moved toward the opening, it tends to force the mustard out of the opening on the article of food which is held beneath said opening 3. The upward movement of the piston is limited by means of the stop 9 on the rod or stem 6 and if desired, the spring 10 may be omitted so that the operator need give a reciprocating motion to the stem by first raising it and then forcing it down to eject the mustard.

'As the device is completely closed ,except for the tiny opening 3 through which the mustard is forced, there is no tendency for the mustard to corrode or encrust about the container, the same presenting an extremely neat and sanitary appearance at all times.

Having describedour invention, what 'we claim is: i a

1. An'article ofthe class described comprising a vessel for containing mustard or a like viscous substance, said vessel'being provided with a narrowed lower end having an exit opening leading exteriorly of the vessel, a piston movable in said lower end and adapted by its reciprocation to directly eject the contents of the vessel through said open ing and out of the vessel, a rod on which said piston is mounted, said piston being composed of a pair of disks, one of said disks being fixedly secured on said rod and beingprovided with a plurality of perforations, the other disk being movably mounted on the rod, said movable disk being imperforate and of less diameter than the fixed disk.

2. An article of the class described, comprising a vessel for containing mustard or the like, said vessel beingprovided with an integrally, formed contracted lower end provided with an exit opening leading eXterilower end, means on said stem moving in' said contracted end for directly ejecting mustard through the exit opening and ex-' teriorly of the vessel, said means comprising a disk fixedly secured on said stem and fitting into the contracted end with a piston fit, said disk being provided with a plurality of perforations, and a disk movably mounted on said stem below the fixed disk, said movable disk being imperforate and of smaller diameter than the fixed disk.
